Alpha blending on a texture

Hey, Can You please tell what I''m doing wrong with my particle engine here!!! The alpha blending dosn''t work... GL_BLEND is enabled and if I enable the glBlendFunc the texture isn''t showed at all I''m using TGA files, which are created as Mipmaps My Code -> //glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glColor4f(glParticle.pColor[0], glParticle.pColor[1], glParticle.pColor[2], 1.0f); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, pTexture[0]); glBegin(GL_TRIANGLE_STRIP); glTexCoord2d(1, 1); glVertex3f(glParticle.pPosition[0] + 0.5f, glParticle.pPosition[1] + 0.5f, glParticle.pPosition[2]); glTexCoord2d(0, 1); glVertex3f(glParticle.pPosition[0] - 0.5f, glParticle.pPosition[1] + 0.5f, glParticle.pPosition[2]); glTexCoord2d(1, 0); glVertex3f(glParticle.pPosition[0] + 0.5f, glParticle.pPosition[1] - 0.5f, glParticle.pPosition[2]); glTexCoord2d(0, 0); glVertex3f(glParticle.pPosition[0] - 0.5f, glParticle.pPosition[1] - 0.5f, glParticle.pPosition[2]); glEnd(); glDisable(GL_TEXTURE_2D); glParticle.pPosition[0] += glParticle.pSpeed[0] / 1000; glParticle.pPosition[1] += glParticle.pSpeed[1] / 1000; glParticle.pPosition[2] += glParticle.pSpeed[2] / 1000; glParticle.pSpeed[0] += glParticle.pGravity[0]; glParticle.pSpeed[1] += glParticle.pGravity[1]; glParticle.pSpeed[2] += glParticle.pGravity[2]; glParticle.pTransparency -= glParticle.pTime;
