Way to open/import an SVG file with Photoshop CS2 or CS3

Use Inkscape! It's a really powerful graphical tool and it's free

Can I open/import *.cdr (Corel Draw Vector drawing file) files in Inkscape?

You can use the UniConvertor for converting CDR files and some other formats to SVG. In Inkscape 0.46, there's an input extension that will allow you to open or import CDR files directly from Inkscape if you have UniConvertor installed on your system.

If you can't run UniConvertor, you can try this workaround:

• Open the CDR file in Corel Draw. Save it as binary encoded CGM* file. It will save only vector graphics. It will not save bitmap graphics.
• Open the CGM file in OpenOffice Impress. Copy to Open Office Draw and insert original JPG or another bitmap graphics. Save file as ODG And you can continue in Open Office Draw program.)
• Select all (CTRL+A)
• Export as SVG.
• Open SVG file in Inkscape and correct mistakes if they appear.
• Note: OpenOffice will open only binary encoded CGM files in Impress. If the CGM is encoded using clear-text encoding, it will be opened in OpenOfice Writer, thus rendering the next steps invalid.

One has an .svg extension, and the other is .SVG. Could be as simple as that.
