Update Image
 

I think the image management page should has a feature that will allow admins to update a certain image with a new one and then it will automatically search the database and update the tables as well in case the image extension is different which means that the url will be different too

That worked on MA... because I forgot to colour a section of an adoptable, so I deleted it and re-uploaded it.

I think it only works if the file name is the same... and I'm not sure if it works for Mys too.

Well, it's impossible for me to remember the exact name of the old file and plus I wanted to update the file with a different extension, if I wanted to update it with a same extension file I would just rename the file to the same name as the uploaded file on the server and replace it through FTP upload

An image management page? I think its doable, may give a try when I am less busier.
