Let's start:
1 Kartinki must be unique, search engines can see the originality of the photos of artifacts(but if you write about a new model car like the overview, where you take the original photo?) the goods can not take a picture, but then see how are your users, and may not see need Delta products, the pictures that you took from the Internet
2 Size need to be selected on the basis of logic (if you take the PC now is basically a resolution of 1920 x 1080) + images can be the same and compress without losing quality https://tinypng.com
3 Need alt, this is exactly the title of the pictures are not so important. And it makes sense to do the signature under a photo (improves usability)
4 about the name Sayo pictures, see the market, if it's CIS then just do a transliteration

>>there is the opinion that you need to sign in name reference library + the word photo or image transliteration.
And without that may be fine if you have the correct title and alt and href pointing to other data in different formats(sizes) of the image. If You can do CNC for the pictures - definitely not worse, so the answer is - if you know how to do, if it is consuming that much sense. I can not imagine such as You in Bitrix will.

>>How justified to write the word photo or image or logo?
You have the address of the file? If Yes, then the special effects You will notice, again if You do something that's for SURE - the search engine You do not penalize for it. And on account of the reward can be, with significant don't count.

>>What size photo should be?
>>-there is an opinion about what photography should be high quality and not at the same time, it should not be too significant.
The answer is - do it efficiently for people. In adaptive choose the desired format(size) to fit the device, while let the opportunity to see Lupe in a better image.
And precisely will not be worse if You are going to use optimization program, which will reduce the size without losing quality, at least google shouts that it loves.

>>3 the Desired alt, this is exactly the title of the pictures are not so important. And it makes sense to do the signature under a photo (improves usability)
And alt and title are a plus. Context the environment has a value proven in practice that appeared in the preview of images in search engine Yandex, a search for phrases from the environment.

>> Why do some sites write your URL on their images?
Some unique and copy protection

>>They also say that all pictures must be unique. Does it make sense to photograph all the products your online store?
If clear on the issue - definitely a plus. Generally it is strange that he came, You want other people's photos of similar goods is whether to place?

For an online store best JPEG (universal) or PNG (if you want high quality, but may have problems with the download).

At the expense of download speed, you can reduce using the services of image compression. For example, https://tinypng.com/

An example of the correct variants of the name of the file:
kedi-convers-krasnie-80.jpg;
kedi-convers-krasnie-front.jpg.

Example meta tags (alt and title you can do the same):
alt= ”converse sneakers red rice. 1”
alt= ”converse sneakers red top view”

But better, of course, detailed and not spamno:
alt=” Popular model of sneakers converse all star red — top view ”

if (PNG if you want high quality,

no one needs it, nor high nor secondary)))
a JPEG 75-85% looks the same, are you talking about? monitor 4K one designer, the other 999 is the ordinary user with 1920-27 monitor...
but Google for images of PNG cut from 20-40 points - Darien.Keebler commented on March 23rd 20 at 19:17

Solution
1. when you search for similar images, the image size should be the maximum. because the search appears larger. even if the photo is the same, even if the photo quality will deteriorate.
2. should be clearly stated alt 1-2 words, no need to spam the Alta stuff.
3. the image search will still consider the total weight of the portal, and the first results will not put pictures on the site with the attendance of 10 per month, only if for the smallest queries.

before needed uniqueness, as now I do not know. 2019 in the yard, to lower the site in the results for non-unique a picture is too easy. another thing that I've noticed that sites with a minimum attendance of say a small edition publishing chipaway news applying unique photos were in the top. in the top will be a greater edition with the copied picture.

all these algorithms are clear and known only to the developers of search engines. any SEOs who make search SCIENCE just throw dust in the eyes. during the work with SEO, you may notice different regularities, but no clear laws because the algorithms are constantly changing and known only to the developers.

again from the day chattering...
immerse yourself in the real world!
For example, you have on page FIVE of the pictures.
How, then, to call these five files??)) Add the numbering?Ooooooooooo
You will have a disastrous turnover, content writers...
again, immerse yourself in the real world! Adequate engine renames the uploaded file -at least it increases the safety
Well it's still not the hands are done, and automatically. Therefore, the content writers it is generally not reflected. Do not interfere when saving to take the real name of the uploaded file and add to it some unique sequence of characters before the extension (and / or number, not with your fingers). - Geoffrey.Runte commented on March 23rd 20 at 19:21

I tag <picture>use. In src put 600 pixels wide and Poitou, then in the source incrementally for different screens 800px width if (min-width 768), 1200px (min-width 1024) and 1600px (min-width 1440). If the picture is text, starting with 1024 and in png format.
