Topic: Images not staying loaded

When you go to my page with an embedded gallery it loads up that's fine.
For some reason when I click on thumbnails it re-loads the image (I can see this both because you can visually see the image reload, and developer tools shows the script hitting the webserver for the image)
Clicking away from the image to another one, then clicking back to it causes it to load from scratch again.....

Re: Images not staying loaded

An image which is currently selected does not have its corresponding thumbnail link disabled.
If an image is requested, then the link will naturally lead to the location of the image on the web server. However, depending of the value of the imagePreloading configuration option, your browser may have the image cached.

Try the following.
Create a sample gallery with large images (large enough to have a significant and noticeable loading time, for example several MB each) and configure it so that the gallery has at least two thumbnail pages.
Set imagePreloading="PAGE".
Upload the gallery to your web server, load the gallery in a browser and go to the first image on the second thumbnail page.
You should notice that the image takes a long time to load.
Now select the next image (on the same thumbnail page) and then select the first image on the second thumbnail page again.
You should notice that the image appears instantly this time (rather than being loaded from scratch).

I hope this makes sense.

Re: Images not staying loaded

I have imagePreloading = "ALL" at the moment.
Will try PAGE but I figured ALL would be even more effective...

Re: Images not staying loaded

imagePreloading="ALL" should start preloading all images in the gallery as soon as the gallery is loaded (which might take some time) but once the images are preloaded, they should display quickly when selected (rather than having to be loaded from scratch from the web server each time).
If you have a lot of images in your gallery and you find that the initial load time can be quite slow, then I would recommend setting imagePreloading to PAGE instead of ALL but it depends on your gallery as to what works best for you.
As long as the image has been preloaded, it should not have to be reloaded from scratch from your web server.
