Image Compression

Hi Brandon, 

Would you be able to change the quality setting at all? I'm not sure how big/clear the images are to begin with...so this may not be an option.

In this thread, Antony suggested editing the pictures in something such as Photoshop allowed him to cut down the total file size. 

Thanks for the reply, Ashley, but I'm assuming that will change the quality of ALL of the slides/images, and I'm trying to compress one slide in particular. I'd be fine with changing the quality of these images if I could do it for just this slide. Is that possible?

Hi Brandon,

Yes, it's a publish setting - so it will impact your whole course. Did you review Antony's suggestion in this thread?  Possibly others in the community have suggestions on how to reduce the overall size of images - but those were my best thoughts based on what I've seen here.

If we can compress image without affecting the quailty of original document, then we had better to choose image lossless compression. You mentioned jpeg compression, yes, JPEG compressing software is based on Wavelets, it is able to present images at different resolution and sizes. That is to say you can display full size, full resolution or half size. And Jpeg compression gives the smallest image size.  As far as I am concerned, you may also try jbig2 compression that is popular for many users. It supports lossy and lossless image compression modes. You can try to save your slides into both image forms and compare which one is smaller.

Thanks Timothy for sharing both of those here with us. I'm not certain if Brandon is still subscribed to this thread so you may want to send him a private message as well.
