Writer - How to put image side by side without overlapping?

edit

I seems to solve my problem. However, it become ridiculous if I rotate the image 90° before anchoring it as character.

In this case, put your page in landscape orientation: the rotation is transferred to the paper sheet and you insert your umages without rotation.

I think it does not serve my purpose. In fact, I do not care if the image is landscape or portrait, as long as I can arrange as many as possible to save paper, print them, then cut them from the printed sheet. Or maybe I don't get what you mean by changing the page orientation to landscape.

Now that you tell the whole story, I think Writer is not the right tool for what you want. I had a similar need to print photos on a printer with paper rolls (not pre-cut sheets of paper). I used GIMP to set my pictures side by side within the width of the roll (nearly 1m!) and them print stripes of roughly 40cm (the maximum that could be fed into my manual guillotine trimmer).

The advantage of using GIMP is you can adjust picture definition & dimensions, crop and color-correct the images. You eventually fine control the inter-image margins if needed.

@Livy I have to agree wholeheartedly with @ajlittoz . Why would you ever use a text processing program (Write/Word) for image processing, especially when your document has no writing?! Do you use a wrench/spanner to drive nails into boards? If you don't have GIMP or Photoshop (both are overkill for what you'd like to do), use MS Paint (or whatever its called these days). Or you could use LibreOffice Draw instead of Writer, which is far better suited to the job.

@gtomorrow Because I can easily preview my images on A4 size before printing. For some images, I need exact size (ie: 10cm * 8cm). I highly doubt if the programs you mentioned can print an image at a precise dimension, or they have such preview features.

@gtomorrow: good point, I completely forgot Draw for simple tasks. However, for photo job, if you want to avoid Moiré effects and other adverse artefacts, you better convert first your pictures to account for differences in dpi between the printer and the camera. You can also control quality loss, deblur and eventually enhance contours. In my case, I had to do all that because the final file size was in the range 500-800 MB. Needless to say, the printer does not understand .xcf or .psd. The file had to be .pdf which seriously inflated the original.

@Livy: GIMP is FOSS (freely downloadable) and is pixel-accurate. DPI is set independently. BUT (and this is a very big BUT), you'll need some time before you can something useful with it. Even if all you want is positioning rectangles (your pictures) in the working area. I 'm more confident in GIMP's ability to respect an exact image size than in LO. I had trouble with drawings (built in Draw) pasted in Writer with different dimensions (and this is the same suite!).

In GIMP, you have a zoom which is equivalent to preview. You can also set "magnetic" guide lines to reliably align your pictures. In fact, you can build a template files with all your picture positions preset and ready to accept images exactly where you desire them.

@Livy I have touched a Windows box in years, so I don't know what capabilities Paint has for print preview but I find it hard to believe that it wouldn't have a such a feature, basic as it may be. Regarding LibreOffice Draw, just as a test, I did exactly what you've been doing in Word, that is, I placed four images in place on an A4, snapped to grid, resized to exact measurements (10x8 cm) and rotated if necessary, then exported to a PDF file in high res 300 dpi...all in less time than it's taking me to respond. The right tools for the job. But as my friend's grandfather used to say, "You want some advice? Do what you want."

@Livy I will admit, if I read your original question correctly, is that LibreOffice Draw won't import multiple images and automatically place them on a page...so, y'know...that's that.
