Several of the jAlbum filters have outlived their usefulness. They trigger reprocessing and reuploading of all the images, but what they're accomplishing can be done much more easily with universally-supported CSS, which requires no image processing. Not a high priority, but these should all eventually be removed, or at least turned into "no op" methods:

BlurFilter. CSS equivalent: img {filter: blur(3px);}, plus overflow: hidden; on the containing element.

GrayScale. CSS equivalent: img {filter: grayscale(1);}. This option should also be removed from the Effects panel.

MarginFilter. CSS equivalent: img {border: 10px solid rgba(170 170 170 / 0.2);}. In this case, the CSS is superior because the margin/border doesn't expand or shrink along with the image when placed in a responsive layout.

ZoomFilter. CSS equivalent: img {transform: scale(1.3);}, plus overflow: hidden; on the containing element.
