Dear folks,
I am feeling my way forward with photograph creation for showing in a gallery, by building a flat box and placing the uploaded photo on it. Lets say the desired size is 8 metres x 3.6 metres, but this varies of course. When I place the uploaded photograph, sometimes it comes up just fine, but other times it appears as a heap of tiled or repeating tiny photographs, which is really annoying. May I ask why this happens? Anyone know? The original image might I upload might be 800 x 350 pixels, to 1200 x 400 pixels, and the uploaded image might appear as 1024 x 256 etc. I don't understand the ideal resolution for uploading in pixels, and I dont understand how sl alters these to fixed ratios and sizes, nor the ideal original resolution for best sharpness in sl, but the main concern now is to get just one photo showing on a frame, and not a whole heap of tiny repeating photo units.
Thanks, Turlough

in the edit menu there's a checkbox called 'stretch textures'. Make sure that's checked when you're sizing your prim. If it's not checked the prim preserves the scale of the texture, hence, causing the repeat to occur. Also, to fix it, in the texture tab of the edit window set the horizontal and vertical values to 1.0

In the Textures tab, there are boxes for repeats, rotations, etc...Experiment with those.
Use the lowest resolution (pixels) that looks good.

sl is limited to open GL's texture dohickyamabobs
(trying to get technical here)
which boils down to "the magical powers of 2" which really all computer graphics deal with in some form or another, your valid sizes are
8
16
32
64
128
256
512
1024
and any combination of them, if your source image is not one of those sizes SL will automatically resize them for you, and usually does a good job at it, altho theres always a quality loss when resizing, which if your making an image from scratch its better to just use one of the powers
