@Gargron IO200 is a very nice CMS for photographers. Self-hostable with low prerequisites, though not FOSS. 😕 The Need for your own photo place over pixelfed etc. is understandable. Its not enough to present photos in a kind of feed alongside creations of others. Especially if opening your archives it is good to publish the content with the correct date from the past. This CMS is derived from the great Koken which unfortunately disappeared. https://www.io200.com/
