Ok, I made a painstakingly slow and simplified version of what I do w/ Imgur. I use it for all my forums that don't store images for me, and it works. Others may be able to improve this process, but it works for me and it goes like this:
After I log in, I click on "Images" in the top right:
Then I click "Add Images"
I then click and drag the image I want into the window that pops up:
Then I open the file that I just uploaded by clicking the pencil icon and hitting Edit:
When that window opens, I can crop it or resize, and save:
Last, I click on the image after the save, and copy the "Direct Link" URL:
Then I come over here and post it as an image, just like you're used to doing with photobucket, and you end up w/your masterpiece posted for the world!!
