Blurred /compressed images

Hi there, i’m trying to paste some screenshots of a remote terminal, i’ve been trying various resolutions and also put the images in the lightbox, and even though it’s now readable and zoomable, the images are still blurred.
I’ve downloaded the image back from asset manager and notice that there is an ‘original’ ‘large’ ‘small’ and ‘thumbnail’ version of my image and i suspect that evolve is using ‘large’ … I can see that even the large version is blurry, so what I would like to do is force evolve to use ‘original’ . How can I do this?

Sorry; I don’t know the exact answer to your question but I have an alternate solution.

If you host the images elsewhere, e.g., AWS S3 Bucket or HubSpot, etc., and then link to them (rather than directly uploading them into the Course), they retain superior quality.

I too was not satisfied by the compression of images initially but switching to this method solved that.

It can also greatly reduce the file size of your course as it won’t directly contain the images themselves.

What file format are you using for the image? jpeg or png?

jpg. But i’ve seen a similar post from someone else who tried both formats and it hadn’t made a difference. I mean ultimately the problem is with whatever the default compression algorithm is making the images blurry coz my original file is only a 100kb or so, so there really isnt a need to compress it.
I think i’ll go with @uniquenospacesshort 's suggestion for now and store the images on a gcp bucket and refence it via url, though i suspect to the end user that will look like the picture loads separately to the rest of the material (if that’s noticeable - let’s see).

Anecdotally, I think the picture loads more quickly when hosted externally as interactions between the course package and the LMS cause slowdown even if the images are included in some (compressed) manner within the ZIP file.

But, it could be prudent to do a side-by-side of load times to confirm this.

the other option seems to set image size per device, the desktop version does appear clear if I upload the image again… but it means we have to assign the image 3 times, desktop, tablet and mobile, and then 3 times again if you choose to use the lightbox.

Well, PNG is a ‘lossless’ format so shouldn’t result in the same loss-of-quality that the JPEG compression system uses.
