Adobe Portfolio - thumbnails and image sizes

[DistantPlaces]

Hello,

My portfolio has become slower loading over the months. Especially scrolling with meanwhile 130+ images under one page gets tedious until all thumbnails are loaded. I am not fully understanding how portfolio works yet, so I'd like to reach out to the community with the following questions:

• If I upload an image, are the automatically generated thumbnails downscaled versions or the full versions just displayed smaller? The fact the images take long to fully load makes me believe these are actually not separate low-res versions but the actual original images. Thumbnails should defnitely load faster and the difference between 50, 100 or 150 should not be that significant ... or am I missing something? I've also noticed that the page only loads the immediately visible thumbnails and not the full page, one needs to start scrolling to trigger loading other thumbnails.

• In past years I have uploaded many images with width 1920px, but recently, after upgrading my camera and my monitor, I have also started uploading more in 3840px. Image sizes are now exceeding 10MB frequently. Is this overkill? At present, most of my expected viewers do not have a 4K monitor yet but it might change over the years, so I thought I might save myself the hassle of uploading/organizing twice (first all in 1920px and a few years later exchanging all files with 3840px versions sounds like a lot of effort). Obviously, this is a very subjective matter but I'd be happy to hear more opinions to see if I am in the same ballpark or on the upper end with my file sizes.

Side note: I only use Adobe portfolio as a hobbyist and am not depending on a perfect client experience for my visitors.

Adobe Portfolio is not supported on these forums. It's possible @Nancy OShea might know, but your best bet is probably the Portfolio support site.

@DistantPlaces,

Depending on image file size and quantity of images on each page, your site may indeed load slower especially over slow internet connections.  Best advice, optimize images for the web to reduce file size before you upload to Portfolio.  I use Photoshop's  File > Export > Export As panel to scale and reduce file size. My Cover Images are well under 200 KB which promotes a faster loading landing page.  See screenshot.

If you use LR to auto export Albums, optimize web images and select only your best work, not your entire photo collection. 

Hope that helps.

Thanks and sorry for posting in the wrong forum. Most has been answered. I am still wondering if the previews are thumbnails or the same images just shown in smaller scale. From what I have read so far it seems it is the latter, which would suggest another strong reason to downsize the images more.

I will follow up in the my portfolio help page.
