How to Fix Image Upload Issues in Forum Threads

I have been trying to upload some high resolution photos of my new home gym setup but I keep getting an error message saying the file is too large. I am using a standard DSLR and I have already tried resizing the images but the forum still seems to struggle with them. Is anyone else in the US or Canada having this problem lately?

I am wondering if there is a specific file format that works best. I am currently using JPEGs but maybe PNG would be more stable? I have seen some members post massive galleries and I am not sure how they are doing it without hitting the limit. It is quite annoying when you want to show off your progress.

Could we perhaps get an integration with Imgur or another hosting site to make this easier? I know we can link to external images but it is much nicer when they are hosted directly on the forum for longevity. I have seen too many old threads with dead image links and it ruins the archive.

I am hoping one of the tech guys can chime in with a fix. I have a lot of content I want to share including some video clips of my personal records but I am stuck at the upload screen. Any advice on settings or workarounds would be amazing.
