Change white background to an image in bulk - colors

I have about 10000 photos of shoes with white background behind them.
I want to add tiled logo on each photo instead of the white background, but I don't want to touch the shoes themselves. Only add image instead of white background. I need to do it in bulk.
Are there any watermark softwares or any tools to achieve this? Or how to do it in Photoshop?
In Photoshop there is such a tool to select a color and change it to another color, but it doesn't allow to change the color to an image...
Thanks for your help in advance.

How to transform a Grayscale background SVG, to white or black colors

I have Gray SVG icons next to each Menu item (inherited from another project) and displaied as background.
I need to show them black or white but I don't how to achieve this.
As backgrounds I can't use fill css property. I tried with filter:brightness(100) to make them white but I loose anti-aliasing (and analogue with filter:brightness(0) to make them black).
Mask has still serious compatibility issues (e.g. Firefox does not allow external svg).
I tried also to import them as data-uri with LESS feature, but it was unuseful, so.... any suggestion?

Changing only some path/group fills in a background image using svg-sprites

I'm using svg as a background image (logo) in a WP menu plugin and i want it to change a color (fill) when hovered. As it's a free version of the plugin i can't use image, object etc - i have to use my svg as a background image. I've to support IE (9+) so masks/filters are out of question and i'm pretty much left with svg-sprites. That's okey, i know how to do it (using use/xlink:href).
But now comes a tricky part. I want my svg to change only fills of some groups/paths while hovered leaving others untouched. I can only change colors of all paths/groups together in a background image with svg-sprites afaik. Is there a way to do it? Thank you in advance!

IS Google ignoring white text with dark background?

My Website iascoachingindia.in have some coloured boxes with white text on, however background colour is dark and clearly visible to human eye, but I felt Google proffered text which is black in text with white background.
Please anybody have some experienced in the same??
Google can crawl and index all the fonts and color, but the most important thing is to avoid make it spammy by adding the same font color with the same background color.
Also if its with the same color, still Google can access them and index them but you will get a penalty.

How to display a .bmp in an NSImageView for MacOs so that a certain color is transparent?

I have some .bmp files that have some color (maybe black) that is supposed to show as transparent when the graphic is displayed on top a form, so the form color comes through the transparent areas. But by default, when I put these images in an Image View, the black/transparent areas show up as BLACK!
I'm thinking I need to either:
- alter how the NSImageView shows the image, so that a certain color is transparent, or
- modify the .bmp files somehow to make that color suitable for transparency in an NSImageView
But I don't know enough about graphics files, transparency(alpha), NSImageView, nor the image editing tools. I'm trying to use Gimp, but...not sure what I'm doing yet. It seems like there is already a color that should be transparent in the current .bmp file.
I'm sure its something simple for setting NSImageView, or editing my file, or perhaps making a mask for the image, but I don't know how yet. I've looked at various filters in IB for NSImageView, but have not found where to set the transparent color, nor how to grab that color from the image file to make sure I use the correct value.
Thanks in advance for any assistance. (I tried to post some images, but because I'm new, I could not.)

I'm not a Cocoa developer, but in Gimp try adding an alpha channel to your image (a layer mask, perhaps) then saving as a 32-bit PNG image (with an alpha channel), then load that PNG directly into your NSImageView. If you want to make the black pixels transparent in Gimp use the magic-wand tool to select them (use magic-wand with 0 tolerance) and just delete the contents of the selection then save as a PNG directly.
