I've been working on a few projects that involve applying the same changes to lots (hundreds or even thousands) of PNG images.  I need to keep the exact same file names, keep them as PNG, and make the exact same changes to all of them.

It would be really helpful if I could easily apply these changes to all of the PNG images at once.  Is there any way to do this without having to watch hours of scripting tutorials or any other convoluted processes?

Is this Forum available in dark mode also? 

I had this cropped image that I could not get to print in the center of a letter size 8 1/2 x 11 page no matter what settings I seemed to alter. The Image always came out printed onto the top left hand corner of the page. The printer is an HP OfficeJet 8600. In the File/Print dialogue, then in the "Image Settings" tab it looked like this:




As you can see in the "Preview" window it shows the image centered in the middle of the page.

I finally figured out that it was the page margins that needed to be edited. When I look at the page margins they were all set to Zero like this:




What I had to do was go to File/Page Setup and set the page margins to match the image "Position" settings in the File/Print/ Image Settings tab like this:




Then the image finally printed in the center of the page. I want to mention also that checking the "Ignore Page Margins" box in the File/Print Image Settings tab had no effect on centering the image before I edited the Page Margins settings in the File/Page Setup section.

The "Ignore Page Margins" box is underlined in Red:





It seems that this is a bug. Checking the "Ignore Page Margins" box should set the position according to the "Positions" settings dialogue regardless of what the "Page Margins" are set to for the image, cropped or not.

Hey, guys! I'm new to Gimp - making the transition from Paint.net - and I need to find a tutorial on how to create images for the purposes of conveying information. Or maybe one of you can help me: I know how to add text to my images, but I want to underline the text and add a line from it to an area that I've encircled in the image. How do I do that? Thanks in advance!

I would like to manipulate a picture of a group of people in which one person is missing. I also have a picture of that missing person, scaled down to match the size .My problem now is to introduce the individual's head into the picture of the group such that the manipulation cannot be seen, i.e. I need to copy the contours of the individuals head into the group picture, cut it out and then copy the head as a new layer  into the picture of the group. Is that possible?
I hope I've described my problem clearly enough. Of course, I appreciate any suggestions to achieve my goal on another way. Thanks so much!

hello, i am new to this forum.  i just began to use the new Gimp v2.10.12 and i miss the c2g function i made use of for many years in v2.8.  where do i find Gegl's c2g ?

Does anybody have a updated version of the Script "Psychedelic rel 0.03" for Gimp 2.10? It's giving me an error "Error: eval: unbound variable: LINEAR".  I will appreciated if anybody can post here a Updated version for Gimp 2.10.

A lot of the how-to videos I have seen assume you know where they are getting this or that file to download or they say, "Take the file you just downloaded..." What file, where did it come from, etc".  Registry.gimp.org is no longer running but that is where a lot of these 'Help' sites send you.  Somebody, please, tell something usable, PLEASE.

Hello Smart People,

I really need help. I’m trying to recreate and tweak a pattern tile that I originally made using Illustrator and Photoshop. 

I saved all the AI files as svg’s before I ended my subscription with adobe. (All line drawings) They’ve been working well in Inkscape, I’ve also added new images I made using the pen tool in Inkscape, now the problems starts when I try to copy and paste to Gimp. They lose all transparency, both old and new drawings.
I’ve tried the normal cut and paste, paste as new layer, duplicate and paste (everything that can be found on google search). I tried opening the svg file in Gimp, I tried saving as a png and opening in Gimp. 

(I need them transparent so I can layer the images over each other)

I eventually selected and exported each individual line drawing as a png, then opened each as new layer in gimp, they are now transparent line drawings. But when I scale up the induvial drawings they get blurry, I’m guessing it’s because they are no longer vector lines, (which is why I tried to make them vectors in the first place). They were scaled to the right size that I need when I exported them in inkscape, but are very small on the canvas in gimp which is the same size) 
So either I need a solution to enable the png images to be scaled UP or figure out why my vectors aren’t copy and pasting into gimp as transparent.
I'm using windows 10, with 64 bit, and Gimp 2.10

(Please don’t suggest I redraw them in gimp because this is weeks and weeks of work, and need the pattern in the next couple of days) I’m not the most computer literate person, so please give very detailed instructions for solutions (I work best with pictures)
TIA for any advice and help.

I am just trying to find a setting that will allow me to paint with gradually darkening effects over each pass, while holding the mouse button down, and not having to keep clicking to increase the opacity/strength. Blender 3D calls this mode "accumulative strokes" I believe. Id like to lighten darkened areas and be able to evenly blend the strokes with the dodge/burn tool, starting with a very low strength and working its way higher. Thanks!
