Ok, so I really like this, but this directory has a lot more than 45 images. Let's say it has 180. That's four of these pages, so Page > Copy for 3 copies. Now, select ALL the frames, including the first page, and run the script again, and ''don't forget to set width to 100'' (but remember, if you do forget, just run the script again with the right setting, since all the frames will still be in the same X,Y positions). Be prepared for time to pass while this is loading so many images.

This article is part of the Scripts series.

Here is another script to automatically load images. Rather than the set layouts that other scripts generate, this one relies on the user to have a number of image frames created and selected, on one or more pages. You then select a directory of images. If you run out of frames or images, the script quits. Meanwhile, if you have Python Imaging Library, it will resize your frames proportionally to the image (as written with an arbitrary width of 250 points). What this means is that you could just have tiny frames, where you mainly are selecting some X,Y position on the page for the frame, not worrying about sizing it.

As stated in the USAGE notes, if you select your frames in the Outline dialog (note that you select multiple frames with Ctrl-click in the dialog, as opposed to Shift-click on the page itself), it can be easier than scrolling down the physical pages.

USAGE
Before running this script, you should have created and selected one or more image frames.
Run the script, after which the script informs you of your selection number, then asks for a 
directory.

Images are loaded from your chosen directory, and frame size adjusted to 300 points width, and
height adjusted proportionally according to the image size (if you have PIL).
The script will quit either when you run out of selected frames or run out of images in the
selected directory.

HINT: Using the Outline dialog can facilitate frame selection, especially when you are selecting
frames on more than one page. The order of selection doesn't seem to matter, with the order 
of filling being alphabetical according to name of the frame.

Mods

If you want to choose the width or maybe even opt out of resizing, add this just after the line nrimages = len(images):

frame_width = scribus.valueDialog('Size for Width', 'Change this to the standard width you desire, in points.\nChange to 0 to opt out of resizing.',"250")
if frame_width == "0":
    pil_found = 0 # now you pretend you don't have PIL
frame_width = float(frame_width)

Then, farther down, make this edit:

        scribus.sizeObject(float(frame_width),float(frame_width*ysize/xsize),currentframe)

Other Notes

One way of quickly setting up a page layout for an array of images would be to start out thinking about the width of frames you want and how many columns (best to think in points). For example, say I want some thumbnail-sized images, 100 pts wide. The width of my US Letter page between margins is 530 pts, the height 712 pts. So we'll estimate that I will get 5 columns and 7 rows. This will take 2 runs of the gallery.py script.

First I make an arbitrarily sized frame specially at 40,40, where the corner of my margins is. Run the script for this one frame and set frame width to 100. Now select Item > Multiple Duplicate from the menu, pick the Rows and Columns tab, put in 7 row, 5 columns. For the horizontal space we'll let Scribus to the math for 4 spaces with 30 pts to work with, and this comes to 7.5 pts. We then just match the vertical space at 7.5 also, click Ok.

OOPS! We can get 2 more rows in, what was I thinking! No matter, since Multiple Duplicate is a one-click undoable operation, so Undo back to our initial frame, go back to Multiple Duplicate for 9 rows, 5 columns, 7.5 pts horizontal gap and we'll make vertical gap 8 pts since we have a little extra space to work with, and click Ok.

Now, we run gallery.py again after selecting all of the frames, make sure to specify 100 pts for width, and there it is:

Now, select ALL the frames, including the first page, and run the script again, and don't forget to set width to 100 (but remember, if you do forget, just run the script again with the right setting, since all the frames will still be in the same X,Y positions).
