This bundle gives you tremendous flexibility for a very low price point. The Watermark and SimpleFilters plugins are medium-trust compatible.

• Get a 2-4x speed boost by using WIC instead of GDI (requires full trust)
• Go nuts with your RAW files, PSD files, and apply advanced filters you'd only expect from Photoshop.
• Overlay (or underlay) multiple text and image layers with the Watermark plugin - anything is possible.
• Auto-trim your product photos with WhitespaceTrimmer, or use SeamCarving to magically change the aspect ratio of images by slicing seams of pixels from background (low-energy) areas of the image.

• AdvancedFilters plugin - Blur, sharpen, remove noise, and perform automatic histogram adjustment. Plus several other cool effects.
• SimpleFilters plugin - Adjust photo transparency, brightness, and apply sepia and B&W filters through the querystring. Nearly zero performance overhead - matrix-based.
