GUI

• The very top bar shows different image sets you can switch between by button or double-click on the zoom-window. (the sets and the images names should comply the naming convention described below).
• Thumbs ribbon allows navigating through the set with a selection rectangle. The selection rectangle is draggable and also zooms in/out on mousewheel, bound to the zoom window view.
• View window shows enlarged parts of the images. Is draggable and also zooms in/out on mousewheel, switches to the next set on double-click.

Adding New Image Sets

• Basically all you need to do is to create a new folder inside image_sets/ with a name of your choice and place all new images inside that directory.
• image_sets/list.txt can be used to add a description of the imageset in list.php, instructions about syntax are inside the file itself.
• image_sets/your-image-set/caption.txt can be used to add captions to all images inside the this particular set, there is no special syntax, just add whatever you want * inside the caption.txt file and it will be displayed 1:1 in html.

• NAMING images: <common-prefix><order-in-set><set-name>.jpeg

Example

img1:  123456789__33-MY_IMAGE_SET-.jpeg 
img2:  123456789__32-MY_IMAGE_SET-.jpeg

<common-prefix> - common number/letter combination for all images in a set.
<order-in-set> - described below - starts with "__"(double underscore), ends with "-".
<set-name> - the name for the current set starts after the <order-in-set>'s "-". Ends with a "-" too.

• <order-in-set>: "_XX-". The current sequence for suffixes is:

__33-, __32-, __13-, __12-, __11-, __23-, __22-, __21-, __63-, __62-, __43-, __42-, __41-, __53-, __52-, __51-, __93-, __92-, __73-, __72-, __71-, __83-, __82-, __81-.

• ImagesInSet = Row x Cols, ImagesInSet<=24(so far))

• You can set to display the set as a table by setting Rows and Columns:

http://<your-address>/viewer.php?path=image_sets/series_2&rows=2&cols=4

When Cols is not set then Cols = floor(ImagesInSet/Cols).
