Here’s a blog post about Imgur Pro features becoming free for everyone:
Link. I can delete my own images with two clicks. There is a Request Deletion option at the bottom of my page, but I would only need that to request the deletion of an image that is not mine. Also I have waaaay more than 250 images visible. I used to have a Pro subscription, but they refunded my last payment when they offered the features for free. Do you suppose you have to request the new options? From what the post says I thought it would be the same for everyone.
I also switched from Photobucket at the time of the “improvements.” Since then I’ve been satisfied with Imgur for posting screenshots and such.
