Fixed issue #9

[IgorShadurin]

Overview

This PR introduces the ability to start with an empty photo album, addressing the usability challenge described in issue #9. With this update, users can delete the last remaining photo in an album, allowing them to initiate a new album without any pre-existing content. This functionality is pivotal for users who want to create a fresh album at new.photoalbum.eth.

Additionally, the PR enhances the user experience by allowing multiple image deletions simultaneously, streamlining the album curation process.

Enhancements

• Enabled deletion of the last photo in an album to support the creation of an entirely new album.
• Implemented multi-image selection for deletion, increasing efficiency in managing albums.
• Refined the "view image" icon visibility during multi-select operations, ensuring a consistent and intuitive UI.

Impact

These improvements significantly reduce the steps required to start a new photo album and simplify the image management workflow. Users can now enjoy a more flexible and user-friendly interface when curating their photo collections.

Testing

Changes have been tested across different scenarios to ensure reliability:

• Deleting the last photo in an album to create an empty album state.
• Removing multiple images in a batch operation.
• Confirming the "view image" icon functionality during multi-select mode.

I just played with this too. Looks nice and we could certainly merge it as is.

However, allow me just one question - is it possible for me to select multiple images without loading them? Suppose I have an album and I want to select and then delete images 1 and 2. I click on the multi-selection button and then I select image 1 and 2. The problem is that I will not have the "delete" button until after image 2 has finished loading.

Is there a technical reason why the loading animation blocks the delete-add-moveup-movedown button?
