I am having issues uploading images on to the gallery. This has been happening for the past 2 days. I am able to upload on mobile but not on PC. This is the error I get after I click continue after I uploaded my image using the uploader: 

How large are the images you're trying to upload and which format are they in? I experienced the same error when trying to upload a 2.4MB PNG file, only to fix it by saving the image as a JPG instead, which brought the file size down to 928KB.

Odd, I've just seen this screen myself. Happened with four pictures, two, and even a single 1.4mb. All are .png, which I've never had an issue uploading (even four simultaneously) in the past. I noticed that when on the Step One "Add Images" page, after selecting my images and letting them load until the little "Done" message appears to the right of them, a small preview of the image usually loads to the left of the picture's name and file size, however now it is not doing this and I am receiving the error. Strange.

EDIT: Just tried the same image as a .jpg as Illusionary suggested, that little preview image loaded immediately and the error didn't occur. Not sure why, but maybe there's just an issue with uploading .png's all of a sudden?

Ok. I have uploaded images in jpg. However, there's a twist to it. you can;t upload any image above 1MB, even on Jpg.

Any issues should be resolved now.
