small imgs to pic
@gabrieleguerrisiYou should convert all the small images to pic. The reason is that otherwise they will stretch in the original app, even if here in the web-preview you can still see them as 100x100 cool images. They won't be cool in the Telegram app.
without pic here is the result of a 100x100 image:
with pic (and th, but same result without it, I just added it to keep the pic cool and centered respect the rest of the content below, as in the original - it's just some styling):
I think this is a bug of the web-preview since the developer can be deceived (happens to everyone the first time), because we all expect the same result in web-preview as in the real app. It should be fixed in future imho.
PS: converting to pic does not mean that you make them smaller, instead you just "tell to the app" that they are already small, in order to let it handle properly!
