How about a photography competition to kickstart the new forum? We would like a photo of your pet (all pets welcome!) at their happiest... This could be snuggled in bed, chewing a bone, playing with catnip, lazying in the garden, on a walk... up to you! You can enter up to two photos each and the Your Pet team will pick three winners. The prize... That will depend on the pet who wins! Something small (probably) but something nice for your pet. Good luck!
If you upload them from a computer the upload (even with the insert button) then they always go up as thumbnail but they can be clicked on to enlarge them. The insert allows you to position them in the post whilst not using it just puts them at the end.
I quite like that as a lot of the photos you can see quite well in the thumbnail but can enlarge if really want to whilst keeping the post size down for scrolling/reading purposes.
To get them larger size I think they need to be a link to photobucket or the like.
Of course I could have misunderstood you & you meant the physical size of the file which has a max of 3MB,
Happy days with Roman, Osiris & Lexie (remembering Chloe & Penny)
