I doubt the TM Image site is converting to .jpeg - it doesn't convert any of my .jpg files to .jpeg..
At the the risk of adding to the confusion here, TM-Img
is now storing files as
.jpeg rather than
.jpg . I noticed it the other day when I uploaded some images and I have just tested it again with two random pictures (one of my trip to Salisbury last week and an example of my recent attempt at cooking.) These both have .jpg extensions on my Windows 11 laptop but TM-img has changed them to .jpeg.
I know this didn't use to happen, something must have changed at the TM-Img end.
However, I don't believe it matters. The .jpeg problem is a bug in this site's gallery forums, but only there. Pictures hosted elsewhere are just image files and are rendered properly by HTML.
As for avatar the size, I wasn't aware that larger images were accepted. Nonetheless I would recommend you resize to 100x100. Downloading a file that is 1000 times larger than needed is a waste of bandwidth, at the server end as well as each viewer.
