Exactly. I do like this forum but that is an annoying problem. EVERY time I post a picture I've used before, I have to rename it. I have pictures categorized in order to find them easier. What do you think happens when I have to rename them? YES, they get mixed up and shuffled round. It is a bad design.
May I offer a suggestion?
What you can do when you want to post a pic that you done before, meaning that you would have to re-name it is:
Copy the pic(file) that you want to post and drop it in a temp folder or even name that folder DC.com temp pics. Then re-name the pic once it's in the new folder with your original pic still safe in it's original folder. Re-name it (mash the keyboard) post it on DC.com then go back and delete the pic from the temp folder so that way you don't have a mass amount of the same pic with different file names.
I also do this method when I do resizing. Keep the original large resolution pic in it's original folder, copy it to a temp folder and then edit it in there and post it. Then go back and delete the edited pic after it's posted on DC.com. If I have multiple pics to post on DC.com, what I'll do is mash the keyboard then use the same charaters followed by a series of numbers like 001, 002 and so on. Example:
Since DC.com only allows 4 pics per post and I need to post more than 4 pics on the same topic, I'll just reply to my previous post and add more pics and continue naming them such as...
Also when needing more than one post to add more pics, add some sort of text or emoji in the field along with the additional pics. The popcorn emoji
seems to be the popular one of choice.
Hope this helps.
