Fixed: Blurry Image after previewing and publishing.
Recently, I also get the same issue and I tried a lot to fix it. Only solution I find out is given as follows in few steps:
1. Do not crop or scale your image in Articulate Storyline.
2. If you want to resize the image. I better suggest you to use Adobe Photoshop for cropping and scaling.
3. Export the image from Photoshop as JPEG or PNG format and Import the image in Articulate Storyline.
4. I repeat.. please do not scale or crop in Articulate Storyline. (if you are facing above issue.)
Thanks & Regards
