I am guessing that most of you guys are posting from phones. I am still using s 1st gen flip phone and posting from a laptop.
All I have to do is click on the attachments, click again on browse to open my photos file. Double click the desired image. Done. Easy peasy, no screwing around with urls or hosting services.
My camera takes photos with large jpg files. When I take photos for the forum, I just make sure the desired image is a small portion of the frame, then I crop down to eliminate about 80% of the original image. Much easier than trying to use a resizing program.
