Gimp Guillotine Follow Up Primer Tutorial
Still on yesterday’s Gimp Image Map HTML Primer Tutorial‘s Gimp themes do you remember us saying, relating to GIMP …
… precursor to being able to break an image into component parts via “Image -> Transform -> Guillotine” or the more enticing, for those web developers out there, “Filter -> Web -> Slice” which effectively does what Guillotine does and writes out some HTML in the form of an HTML table element that includes some “a” link opportunities to do something special for individual images of the new “image jigsaw” surrounded by Guides
… down below? Well, yes, today is a revisit to the “Guillotine” bit of that, because it is all well and good to use “Filter -> Web -> Slice” for a fait accompli HTML table “slicing” approach, but as you can imagine, there are lots of reasons, such as responsive design, why you might want to stop at the “Guillotine” “just give me the images, manperson” stage and from there, do your own thingthang, manperson.
We’re just starting down the road of this today in our “Primer” tutorial, just being able to either …
- image creation method …
- start GIMP and listen out for new images created … we’re hoping via “Image -> Transform -> Guillotine” … or …
- specify your own filespec of images … we’re hoping got there via “Image -> Transform -> Guillotine”
- list those image files …
- show those image files
GIMP being a desktop application, you might have guessed that we’d use a serverside language for this work, and yes, we’re using PHP gimp_guillotine_followup.php today, but don’t show you any live run links because it is more than likely you will use this PHP with a local web server like MAMP (though into the future we may offer a command line mode of use).
So please feel free to download that PHP and/or see its approach via today’s tutorial picture.

Gimp Image Map HTML Primer Tutorial
As we intimated yesterday with Gimp Guides to HTML Primer Tutorial regarding the GIMP image editor’s “Filter -> Web” menu …
… you would also see an “Image Map” option helping out in a similar fashion to the stupendous mobilefish functionality.
… and so we are here today to show you how that functionality works via a PDF slideshow for your perusal. There are options to shape what goes into the resultant HTML’s map element’s area (as rectangle or ellipse or polygon) tag href property link types as per …
… as a very extensive ideas list on top of options to define event logic for …
- onmouseover
- onmouseout
- onfocus
- onblur
… and that there is the option to define exact co-ordinates, and to define the alt attribute and HTML iframe name as applicable, also.
We’ll leave you with the resultant HTML we had GIMP create for us as a result of the goings on in that PDF slideshow (noting that the only adjustment to HTML in out TextWrangler editing session was to point at the image img element src attribute location properly), and we hope this is of benefit for you …

Gimp Guides to HTML Primer Tutorial
The great GIMP image editor has several ways to create Guides, which are the precursor to being able to break an image into component parts via “Image -> Transform -> Guillotine” or the more enticing, for those web developers out there, “Filter -> Web -> Slice” which effectively does what Guillotine does and writes out some HTML in the form of an HTML table element that includes some “a” link opportunities to do something special for individual images of the new “image jigsaw” surrounded by Guides. Within the options of that last menu you would also see an “Image Map” option helping out in a similar fashion to the stupendous mobilefish functionality.
With this in mind, we almost immediately thought of the great Piet Mondrian and his rectangle paintings in primary colours, wondering if by now you could get image downloads of his work, given he died some time ago now. And yes, there at this Pixabay webpage, thanks, we were able to do that and download an image version of “Composition with Red Yellow and Blue” to open with GIMP.
Which ways, then, in GIMP, can you create Guides?
- precise Horizontal or Vertical position specification in pixels (via Image -> Guides -> New Guide…) or percentage (via Image -> Guides -> New Guide (by Percent)…) values
- position via a Selection (via Image -> Guides -> New Guides from Selection) … and today’s method of choice …
- user long hover then drag of the rulers at the top and left for dynamic Horizontal and Vertical Guides respectively
Best for this is that you can see us doing this with YouTube video we made for the purpose on our MacBook Pro using QuickTime Player “File -> New Screen Recording” resultant presentation you can play below.
… and the resultant HTML code snippet, including our bits, produced looked like …
