The script seems to work but makes images take much, much longer to load

This is because there needs to be an image for it to create a button.
There's no need to create a view image button if it's a non- .jpg/png/gif url.

I'm pretty sure that the images I opened were .jpg/png/gif urls.
The image takes forever to load because of the script

So, the loading time is different when the script is disabled?

Yes

Fine, i'll update making the worker function asynchronous (maybe it'll work, depending on browser also).
Tell me if it's faster after updating.

ok
