Jason, you were right. But there is still an issue.
I follow those steps each time and I'm able to reproduce the same issue in Opera each time.
The "automatic opening the last page" thing is an Opera feature that I don't use and is turned off on my computer. You just turn it off in your preferences. I also don't use Turbo. That is also not coded into my page at all.
Thanks so much for the Opera usage info. I read an article that made me think more and more people were using it and my husband started using it as his primary browser.
Jason, you were right. I was only deleting the Disc Cache. I just found where you delete all personal data in Opera. When you said those words I realized where I was going was in the preferences. You are going TOOLS / DELETE PRIVATE DATA.
When I DELETE PRIVATE DATA, Close the browser, Open a New browser, enter the Gallery page and wait for all images to load, the main image DOES load, but when I choose NEXT, NEXT, NEXT, NEXT and go through the images, they load sometimes in the center, sometimes to the left side of the container intermittently.
So, that is in addition to the Reloading the page over and over issue you mentioned.
Glad to know for sure that I shouldn't waste anymore time with Opera on this issue.
